CONTAINER.

Application filed January 26,1924. Serial No. 688,840.

This invention relates to a container or can and the object is toprovide a container which may tightly be sealed to preserve the contentsthereof but which may easily be opened when it is desired to empty thecontents from the container."

A further object of the invention is to provide an easily openedcontainer which has a rim so constructed that even though the containermay easily be opened when manipulated in the proper manner it will notopen when subjected to rough usage incident to packing, shipping, etc.

A still further object of the invention is to provide a container whichis easy andcheap to manufacture both because the closure requires lessmetal than do the usual closures and also because the container may bemade with simple machinery which is not subjected to as hard wear inmaking the container of the present invention as in makng the usualcontainers.

' Other objects and features of the ,invention will more fully appearfrom the fol lowing description and the accompanyin drawings and will beparticularly pointe out in the claim.

In the drawings: v

Fig. 1 is a section through one end of a container showing the containerbod with an opening and a closure therefor aving an unfolded flange, theend of the body also being unfolded and turned overthe flange to holdthe closure in the opening;

.Figs. 2, 3 and 4 are sections through the ends of containers showingvarious other forms which the invention may take.

In the usual container or can the end or closure for the container isheld in position on the body by having the edge of the closure and theadjacent end of the body rolled over and folded upon themselves and uponeach other by a spinningof the metal so that the two are inseparablylocked. It sometimes happens in the rollingv and folding, that both theflange and the body end are so mutilated end of the body is turned overthe flange to catch the flange in between the body and said body end sothat upon pressing downwardly on the closure adjacent the flange theclosure maybe forced downwardly into the container, the flange of theclosure sliding from between the body and body end. The closure will notbe forced away from the body end, however, except by pressure adjacentthe flange because if pressure should be applied to the closure at ornear the center.

the periphery and flange of the closure tend to move toward the centerof the container, which move is resisted by the inturned edge of thebody. Also by turning the .endof the body over the flange of the closurearecess is provided between the body and-body end in which recess asealing compound may be placed to effectively seal the juncture of thebody and closure and prevent the passage of air into or out of thecontainer.

The container illustrated in Fig. 1 is the I simplest form in which theinvention may be applied. In Fig. 1 the body of the container isdesignated at 1 and the open end of the container is closed by a closurehaving a central portion 2 and an upstanding flange 3'around itsperiphery. The body of the container has an upper portion 4 and the endof the body 5' around the opening is turned over the flange 3. Theclosure is of such a size that it fits snugly within the body of thecontainer'but passes easily through it so that when the closure is putin position during the making of the container or when it is desired to,remove the closure by pressing it downwardly into the container theclosure will move I freely but yet when the sure is in the osition shownin the drawings it will frlctionally enga e the upper portion t of thebody and the body end and be securely held in place thereby.

Containers having the structure shown in the drawings may be sealed veryeasily and securely to prevent the passage of gases either out of orinto the container as the upper portion 4 of the body and the body endprovide'a recess 6 to receive and-se curely hold quite a considerableamount of the sealing compound used in the manufacture of cans. The bodyend 5 preferably extends downto the surface of the central portion 2 ofthe closure in order that there be as much contacting surface betweenthe closure flange and the body as possible.

In order more securely to hold the closure in the opening the projection7 is formed on the body and extends inwardly below the closurean'dcontacts with the shoulder 8 formed at the juncture of the flange andcentral portion of the closure. The projection may have any form but ispreferably a beading which extends entirely around the body of thecontainer and projects inwardly. q to such a distance that theprojection nor- When opening the container the closure is I hit by theend of the knife or other-convenient implement around its edge to forcethe closure downwardly to free the flange of the closure from the end ofthe container and the closure then may be drawn through the the recess.

open end of the container so thatthe contents may be emptied. In orderto provide "a convenient means by which the closure may be grasped whenlifting it out 'of the cont'ainer, a finger hold 9 is preferablyfastened to the exposed surface of the closure. The

finger hold may conveniently be a piece 'of flexible tin soldered at oneend to the upper surface of the central portion 3 of the closure andhaving the other end free so that it may be bent into the position shownin Fig. 1 or any other position in which it can be conveniently takenhold of to lift the closure out of the conta ner. I

In making and assembling the container shown in Fig; 1 the body is firstprovided without the projection 7 but having the body end 3 turnedinwardly approximatel to the position shown in Fig. 1. After t e body ofthe container has been formed it is turned up on end so that the rece:s6 is downwar and thena sealing compound is placed in Th s sealingcompound 15- a liquid which is quite fluid when it is made but whichbecomes viscous when it is exsex-ted, from the 6 y us'hd' towardtheiprepa'red" end of the can The closure;

between the contacting surfaces between the flange and body end. Theflange and body end are of such' length that when correctly placed theyhave the position shown in Fig. 1 with the end of the flange entirelyfilling the recess and the body end extending downwardly until it'contacts with the upper surface of .the central portion of the closure.

After the closure has been put in itscorrect position the container isrun through a can machine having a chuck 10 which presses against thebody end 5 and a roller 11 which pres:es against the upper portion 4 oftne body and squeezes the body and body end toward each other'to pressthe flange oetween them. The roller 11 mayhave a boss 12 thereon whichforms the projection 7 on the body end 5 as the flange 3 is caught inits position-ketween the body and body end.

tened in its position on the closure.

In making the container shown in Fig. 2-

the same general procedure is carried out. In making this form, however,the flange 3 of the closure is folded upon itself at 13 but the foldedortion of theflange extends only part way rom the top of the flangedown.

toward the upper surface of the central portion 2- of the closure thusproviding a lip at 14. The edge 15 of the body end, at the pro er timein the process of manufacture, is orced in under the lip 14 to meet theflange 3, thus providing additional means for holding the closure inposition closing theopenin The edge of the body end is turned. in y achuck similar to chuck 10 but having a projection which forces the edge15 over to meet the flange 3. With a Last of all the finger hold 11 maybe fascontainer of this type the recess 6 is quite large and holds aconsiderable quantity of the sealing compound. This is -.an advantagesince when the flange is forced in between the body and the body end theexcess of the compound fills,an'd seals the space under the lip 14 andbetween the edge 15 of the body end and the flange. This form of thecontainer is quite strong. because it has the additional thickness ofmetal provided by the folded end 13 of the flange and the closure isquite securely held in place due to the additional locking action of theedge 15 of the body and being caught under the lip 14 of-the end 13 ofthe flange] The container, may readily be opened, however,'in the sameway that'the container shown in Fig. l is opened, that is by ta pingaround s the closurethe periphery of the closure. is. forced inwardlythe edge- 15 ofthe body quuedyto open end. is-Lforced away from theflangeeS-and slightly spread to permit the end 13] of the? flangeto'pass b and although the. blow rev is form of thecontainer isharder thanthe blow required to'open-the 7 I container. shown in Fi.1,theo, f y t bw ly upp e .1-

In the container shown in Fig. 3, the end of the body around the openingis folded upon itself at 16 to provide a very strong rim where such isneeded and yet have a container which may be opened more easily than thecontainer shown in Fig. 2. The

gasket entirely around the container.

The form of container shown in Fig. 4 is the one having the strongestrim now deemed desirable with" this type of closure.

This form of .container embodies both the folded body-end shown in Fig.3 and the folded flange shown in Fig. 2 with the exception that thefolded portion 13 of the flange extends all the way down until it meetsthe upper surface of the central portion 2 of the closure. The end ofthe flange is thus extended not only to obtain the benefit of the addedstrength but also for the practical reason that the folded end of thecontainer body can not as readily be bent inward under the lip 14 as cana single thickness of metal and also that. it the double thickness ofmetalwere bent in under the lip 14 the container would be much harder toopen since the double thickness-of metal would have to be bent outwardlyas the closure was forced downwardly to free the flange of the thecontainer.

Containers of the type shown and described herein may quite readily be 0cned by tapping around the periphery of the closure but do not readilyopen unless the closure is tappedat or Very near to the periphery. Aseries of slight blows at the periphery will open the container but aclosure from the end of number of hard blows at the center of theclosure will not break the seal. This is due to the fact that when theclosure is given a series of blows at its periphery the flange on theperiphery receives a large down- 5 wardly directed component of the blowwhich forces the flange downwardly out of the recess, while if the blowis delivered atthe center of the closure the flange receives verylittle, if any, of the downward component of the force of theblowdue tothe fact that the metal of the central POI? tion 2 of the closure bendsand tends to draw the periphery-of the closure and the flange toward thecenter which tendency is resisted since movement of the flange downwardby the center would necessitate a buckling of the flange as well as abuckling of the end 5 of the body of the container.

Having thus described the invention what. is claimed as new and desiredto be securedv by Letters Patent is:

A metal container comprising a body open at one end and a closure forsaid open end, said closure having a straight upstanding flange aroundits periphery, the end of the body around'the opening being turned overand pressed against said up standing flange whereby the flange isfrictionally held between the body and the body end, said can body beingindented peripl1-' erally directly below the closure thereby to form onthe interior walls of the body a continuous annular rib wihch assists inholding the closure in place but which is sufficiently resilient so thatwhen sutficient pressure is applied'to the top of the closure adjacentthe upstanding flange at any point the rib will yield at said point topermit the upstanding flangeot the closure to be withdrawn from the bentover end of the body. In testimony whereof, I have signed my name tothis'specification.
